Vriesea plant named ‘BUNVRIOR’

ABSTRACT

A new and distinct Vriesea plant named ‘BUNVRIOR’ which is characterized by a relatively compact rosette of glossy, dark green foliage that gives rise to a terminal, compound spike inflorescence with distichous flowers held within and above the foliage with an orange bract at the base of each branch of the inflorescence and vibrant orange-red conduplicate bracts with yellow tips, subtending each yellow flower, as well as the stability of these characteristics from generation to generation.

Latin name of the genus and species: The Latin name of the genus and species of the novel variety disclosed herein is Vriesea Lindl.

Variety denomination: The inventive variety of Vriesea disclosed herein has been given the variety denomination ‘BUNVRIOR’.

CROSS REFERENCE TO RELATED APPLICATIONS

This application claims priority to the Community Plant Variety Rights application number 2019/3275, filed Nov. 30, 2019, which is herein incorporated by reference.

BACKGROUND OF THE INVENTION

Parentage: The Vriesea variety ‘BUNVRIOR’ is a seedling selection which resulted from a controlled pollination breeding program. In November of 2013, the inventor performed the controlled cross-pollination of a proprietary unnamed Vriesea plant, the seed parent, and a second unnamed proprietary Vriesea plant, the pollen parent, at a commercial greenhouse in Kudelstaart, the Netherlands. Both parents were developed by the inventor and never released to the public. In April of 2016, the inventor observed one seedling from the cross which exhibited unique foliage and inflorescence characteristics and isolated the plant for further evaluation. Upon confirmation of distinctness and stability, the new Vriesea plant was selected for commercialization and given the name ‘BUNVRIOR’.

Asexual Reproduction: ‘BUNVRIOR’ was first asexually propagated by way of vegetative cuttings in July of 2016 and subsequently by way of meristematic tissue culture micropropagation at a commercial tissue culture laboratory in Aalsmeer, the Netherlands. Through 7 subsequent generations, the unique features of this cultivar are stable and reproduced true to type.

SUMMARY OF THE INVENTION

The cultivar ‘BUNVRIOR’ has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, day length, and light intensity, without, however, any variance in genotype. The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘BUNVRIOR’. These characteristics in combination distinguish ‘BUNVRIOR’ as a new and distinct Vriesea cultivar:

-   -   1. Vriesea ‘BUNVRIOR’ exhibits a relatively compact rosette of         glossy, dark green foliage; and     -   2. Vriesea ‘BUNVRIOR’ exhibits a terminal, compound spike         inflorescence with distichous flowers held within and above the         foliage; and     -   3. Vriesea ‘BUNVRIOR’ exhibits a large, orange bract at the base         of each branch of the inflorescence; and     -   4. Vriesea ‘BUNVRIOR’ exhibits vibrant orange-red conduplicate         bracts with yellow tips, subtending each yellow flower.

BRIEF DESCRIPTION OF THE FIGURES

FIG. 1 illustrates, as nearly true as it is reasonably possible to make the same in color photographs of this type, an exemplary plant of ‘BUNVRIOR’ grown in a commercial greenhouse in Kudelstaart, the Netherlands. This plant is approximately 37 weeks old from the time of mericloning, shown planted in a 12 cm nursery container.

BOTANICAL DESCRIPTION OF THE PLANT

The following observations and measurements made in November of 2020 describe averages from a sample set of six specimens of 37 week-old ‘BUNVRIOR’ plants grown in 12 cm nursery pots at a commercial greenhouse in Kudelstaart, the Netherlands. Plants were grown under shade cloth and maintained with a 0.8 EC fertigation program with regular overhead irrigation. No chemical pest measures were taken.

Those skilled in the art will appreciate that certain characteristics will vary with older or, conversely, with younger plants. ‘BUNVRIOR’ has not been observed under all possible environmental conditions. Where dimensions, sizes, colors and other characteristics are given, it is to be understood that such characteristics are approximations or averages set forth as accurately as practicable. The phenotype of the variety may differ from the descriptions set forth herein with variations in environmental, climatic and cultural conditions. Color notations are based on The Royal Horticultural Society Colour Chart, The Royal Horticultural Society, London, 2015 (sixth edition).
